' IMPROVEMENT IN LINKS FOR STEAM-ENGINES.

Specification forming part of Letters Patent No; 174,431, dated March 7,1876 application filed October 7, 1875.

-Be it known that I, GEORGE PALM, of Karns Oity, county of ButlerandState of Pennsylvania, have invented certain new and usefulImprovements .in Link-Motion for Steam-Engines, of which the followingis a specification The nature of my invention consists in theconstruction and arrangement of an enginelink, with friction-roller andlocking-devices, as will be hereinafter more fully set forth.

In order to enable others skilled in the art I to whichmy inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, whichforms a part of this specification, and in which- V Figure l is asideview of my engine-link. Fig. 2 is an end view of the same. Fig. 3-is asection through the link and roller.

A represents the link, constructed substantially in the same manner asis now generally the case.

In this link is placed a flanged frictionroller, B, which works on thewrist-pin or crank, whereby the same will work more free, and withconsiderably less friction.

At the upper end of the link A are two projectin g ears, to a, in whicha short rod or shaft, 1), has its bearings. On this rod is secured ahooked latch, O, which is'designed to hold the 7 link down, instead of aset-screw or lever,

which is generally used on stationary and other engines. The lowerhooked 'end of the latch is to catch on an annular flange or recess, d,

Letters Patent, is-- 1. In an engine-link, A, the flangedfrictionrollerB arranged therein, substantially as and for the purposes herein setforth.

2. The combination of an engine-link, A, a friction-roller, B, therein,and a self-locking latch, G, for thepurposes herein set forth.

3. The combination of the link A, roller B, latch O, cord D, and spring6, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing as my invention I hereunto affixmy l signature this 30th day of September, 1875.
